+
+Destroy a stream.
+
+This module is meant to ensure a stream gets destroyed, handling different APIs
+and Node.js bugs.
+
+## API
+
+```js
+var destroy = require('destroy')
+```
+
+### destroy(stream)
+
+Destroy the given stream. In most cases, this is identical to a simple
+`stream.destroy()` call. The rules are as follows for a given stream:
+
+ 1. If the `stream` is an instance of `ReadStream`, then call `stream.destroy()`
+ and add a listener to the `open` event to call `stream.close()` if it is
+ fired. This is for a Node.js bug that will leak a file descriptor if
+ `.destroy()` is called before `open`.
+ 2. If the `stream` is not an instance of `Stream`, then nothing happens.
+ 3. If the `stream` has a `.destroy()` method, then call it.
+
+The function returns the `stream` passed in as the argument.
+
+## Example
+
+```js
+var destroy = require('destroy')
+
+var fs = require('fs')
+var stream = fs.createReadStream('package.json')
+
+// ... and later
+destroy(stream)
+```

+
+Get the first event in a set of event emitters and event pairs,
+then clean up after itself.
+
+## Install
+
+```sh
+$ npm install ee-first
+```
+
+## API
+
+```js
+var first = require('ee-first')
+```
+
+### first(arr, listener)
+
+Invoke `listener` on the first event from the list specified in `arr`. `arr` is
+an array of arrays, with each array in the format `[ee, ...event]`. `listener`
+will be called only once, the first time any of the given events are emitted. If
+`error` is one of the listened events, then if that fires first, the `listener`
+will be given the `err` argument.
+
+The `listener` is invoked as `listener(err, ee, event, args)`, where `err` is the
+first argument emitted from an `error` event, if applicable; `ee` is the event
+emitter that fired; `event` is the string event name that fired; and `args` is an
+array of the arguments that were emitted on the event.
+
+```js
+var ee1 = new EventEmitter()
+var ee2 = new EventEmitter()
+
+first([
+ [ee1, 'close', 'end', 'error'],
+ [ee2, 'error']
+], function (err, ee, event, args) {
+ // listener invoked
+})
+```
+
+#### .cancel()
+
+The group of listeners can be cancelled before being invoked and have all the event
+listeners removed from the underlying event emitters.
+
+```js
+var thunk = first([
+ [ee1, 'close', 'end', 'error'],
+ [ee2, 'error']
+], function (err, ee, event, args) {
+ // listener invoked
+})
+
+// cancel and clean up
+thunk.cancel()
+```

+
+Encode a URL to a percent-encoded form, excluding already-encoded sequences
+
+## Installation
+
+This is a [Node.js](https://nodejs.org/en/) module available through the
+[npm registry](https://www.npmjs.com/). Installation is done using the
+[`npm install` command](https://docs.npmjs.com/getting-started/installing-npm-packages-locally):
+
+```sh
+$ npm install encodeurl
+```
+
+## API
+
+```js
+var encodeUrl = require('encodeurl')
+```
+
+### encodeUrl(url)
+
+Encode a URL to a percent-encoded form, excluding already-encoded sequences.
+
+This function will take an already-encoded URL and encode all the non-URL
+code points (as UTF-8 byte sequences). This function will not encode the
+"%" character unless it is not part of a valid sequence (`%20` will be
+left as-is, but `%foo` will be encoded as `%25foo`).
+
+This encode is meant to be "safe" and does not throw errors. It will try as
+hard as it can to properly encode the given URL, including replacing any raw,
+unpaired surrogate pairs with the Unicode replacement character prior to
+encoding.
+
+This function is _similar_ to the intrinsic function `encodeURI`, except it
+will not encode the `%` character if that is part of a valid sequence, will
+not encode `[` and `]` (for IPv6 hostnames) and will replace raw, unpaired
+surrogate pairs with the Unicode replacement character (instead of throwing).
+
+## Examples
+
+### Encode a URL containing user-controled data
+
+```js
+var encodeUrl = require('encodeurl')
+var escapeHtml = require('escape-html')
+
+http.createServer(function onRequest (req, res) {
+ // get encoded form of inbound url
+ var url = encodeUrl(req.url)
+
+ // create html message
+ var body = 'Location ' + escapeHtml(url) + ' not found
'
+
+ // send a 404
+ res.statusCode = 404
+ res.setHeader('Content-Type', 'text/html; charset=UTF-8')
+ res.setHeader('Content-Length', String(Buffer.byteLength(body, 'utf-8')))
+ res.end(body, 'utf-8')
+})
+```
+
+### Encode a URL for use in a header field
+
+```js
+var encodeUrl = require('encodeurl')
+var escapeHtml = require('escape-html')
+var url = require('url')
+
+http.createServer(function onRequest (req, res) {
+ // parse inbound url
+ var href = url.parse(req)
+
+ // set new host for redirect
+ href.host = 'localhost'
+ href.protocol = 'https:'
+ href.slashes = true
+
+ // create location header
+ var location = encodeUrl(url.format(href))
+
+ // create html message
+ var body = 'Redirecting to new site: ' + escapeHtml(location) + '
'
+
+ // send a 301
+ res.statusCode = 301
+ res.setHeader('Content-Type', 'text/html; charset=UTF-8')
+ res.setHeader('Content-Length', String(Buffer.byteLength(body, 'utf-8')))
+ res.setHeader('Location', location)
+ res.end(body, 'utf-8')
+})
+```

+Create simple HTTP ETags
+
+This module generates HTTP ETags (as defined in RFC 7232) for use in
+HTTP responses.
+
+## Installation
+
+This is a [Node.js](https://nodejs.org/en/) module available through the
+[npm registry](https://www.npmjs.com/). Installation is done using the
+[`npm install` command](https://docs.npmjs.com/getting-started/installing-npm-packages-locally):
+
+```sh
+$ npm install etag
+```
+
+## API
+
+
+
+```js
+var etag = require('etag')
+```
+
+### etag(entity, [options])
+
+Generate a strong ETag for the given entity. This should be the complete
+body of the entity. Strings, `Buffer`s, and `fs.Stats` are accepted. By
+default, a strong ETag is generated except for `fs.Stats`, which will
+generate a weak ETag (this can be overwritten by `options.weak`).
+
+
+
+```js
+res.setHeader('ETag', etag(body))
+```
+
+#### Options
+
+`etag` accepts these properties in the options object.
+
+##### weak
+
+Specifies if the generated ETag will include the weak validator mark (that
+is, the leading `W/`). The actual entity tag is the same. The default value
+is `false`, unless the `entity` is `fs.Stats`, in which case it is `true`.
+

+GraphQL HTTP Server Middleware
+==============================
+
+[](https://travis-ci.org/graphql/express-graphql)
+[](https://coveralls.io/github/graphql/express-graphql?branch=master)
+
+Create a GraphQL HTTP server with any HTTP web framework that supports connect styled middleware, including [Connect](https://github.com/senchalabs/connect) itself, [Express](http://expressjs.com) and [Restify](http://restify.com/).
+
+## Installation
+
+```sh
+npm install --save express-graphql
+```
+
+
+## Simple Setup
+
+Just mount `express-graphql` as a route handler:
+
+```js
+const express = require('express');
+const graphqlHTTP = require('express-graphql');
+
+const app = express();
+
+app.use('/graphql', graphqlHTTP({
+ schema: MyGraphQLSchema,
+ graphiql: true
+}));
+
+app.listen(4000);
+```
+
+
+## Setup with Restify
+
+Use `.get` or `.post` (or both) rather than `.use` to configure your route handler. If you want to show GraphiQL in the browser, set `graphiql: true` on your `.get` handler.
+
+```js
+const restify = require('restify');
+const graphqlHTTP = require('express-graphql');
+
+const app = restify.createServer();
+
+app.post('/graphql', graphqlHTTP({
+ schema: MyGraphQLSchema,
+ graphiql: false
+}));
+
+app.get('/graphql', graphqlHTTP({
+ schema: MyGraphQLSchema,
+ graphiql: true
+}));
+
+app.listen(4000);
+```
+
+
+## Options
+
+The `graphqlHTTP` function accepts the following options:
+
+ * **`schema`**: A `GraphQLSchema` instance from [`GraphQL.js`][].
+ A `schema` *must* be provided.
+
+ * **`graphiql`**: If `true`, presents [GraphiQL][] when the GraphQL endpoint is
+ loaded in a browser. We recommend that you set
+ `graphiql` to `true` when your app is in development, because it's
+ quite useful. You may or may not want it in production.
+
+ * **`rootValue`**: A value to pass as the `rootValue` to the `graphql()`
+ function from [`GraphQL.js/src/execute.js`](https://github.com/graphql/graphql-js/blob/master/src/execution/execute.js#L121).
+
+ * **`context`**: A value to pass as the `context` to the `graphql()`
+ function from [`GraphQL.js/src/execute.js`](https://github.com/graphql/graphql-js/blob/master/src/execution/execute.js#L122). If `context` is not provided, the
+ `request` object is passed as the context.
+
+ * **`pretty`**: If `true`, any JSON response will be pretty-printed.
+
+ * **`formatError`**: An optional function which will be used to format any
+ errors produced by fulfilling a GraphQL operation. If no function is
+ provided, GraphQL's default spec-compliant [`formatError`][] function will be used.
+
+ * **`extensions`**: An optional function for adding additional metadata to the
+ GraphQL response as a key-value object. The result will be added to
+ `"extensions"` field in the resulting JSON. This is often a useful place to
+ add development time metadata such as the runtime of a query or the amount
+ of resources consumed. This may be an async function. The function is
+ given one object as an argument: `{ document, variables, operationName, result }`.
+
+ * **`validationRules`**: Optional additional validation rules queries must
+ satisfy in addition to those defined by the GraphQL spec.
+
+In addition to an object defining each option, options can also be provided as
+a function (or async function) which returns this options object. This function
+is provided the arguments `(request, response, graphQLParams)` and is called
+after the request has been parsed.
+
+The `graphQLParams` is provided as the object `{ query, variables, operationName, raw }`.
+
+```js
+app.use('/graphql', graphqlHTTP(async (request, response, graphQLParams) => ({
+ schema: MyGraphQLSchema,
+ rootValue: await someFunctionToGetRootValue(request)
+ graphiql: true
+})));
+```
+
+
+## HTTP Usage
+
+Once installed at a path, `express-graphql` will accept requests with
+the parameters:
+
+ * **`query`**: A string GraphQL document to be executed.
+
+ * **`variables`**: The runtime values to use for any GraphQL query variables
+ as a JSON object.
+
+ * **`operationName`**: If the provided `query` contains multiple named
+ operations, this specifies which operation should be executed. If not
+ provided, a 400 error will be returned if the `query` contains multiple
+ named operations.
+
+ * **`raw`**: If the `graphiql` option is enabled and the `raw` parameter is
+ provided raw JSON will always be returned instead of GraphiQL even when
+ loaded from a browser.
+
+GraphQL will first look for each parameter in the URL's query-string:
+
+```
+/graphql?query=query+getUser($id:ID){user(id:$id){name}}&variables={"id":"4"}
+```
+
+If not found in the query-string, it will look in the POST request body.
+
+If a previous middleware has already parsed the POST body, the `request.body`
+value will be used. Use [`multer`][] or a similar middleware to add support
+for `multipart/form-data` content, which may be useful for GraphQL mutations
+involving uploading files. See an [example using multer](https://github.com/graphql/express-graphql/blob/304b24b993c8f16fffff8d23b0fa4088e690874b/src/__tests__/http-test.js#L674-L741).
+
+If the POST body has not yet been parsed, express-graphql will interpret it
+depending on the provided *Content-Type* header.
+
+ * **`application/json`**: the POST body will be parsed as a JSON
+ object of parameters.
+
+ * **`application/x-www-form-urlencoded`**: this POST body will be
+ parsed as a url-encoded string of key-value pairs.
+
+ * **`application/graphql`**: The POST body will be parsed as GraphQL
+ query string, which provides the `query` parameter.
+
+
+## Combining with Other Express Middleware
+
+By default, the express request is passed as the GraphQL `context`.
+Since most express middleware operates by adding extra data to the
+request object, this means you can use most express middleware just by inserting it before `graphqlHTTP` is mounted. This covers scenarios such as authenticating the user, handling file uploads, or mounting GraphQL on a dynamic endpoint.
+
+This example uses [`express-session`][] to provide GraphQL with the currently logged-in session.
+
+```js
+const session = require('express-session');
+const graphqlHTTP = require('express-graphql');
+
+const app = express();
+
+app.use(session({ secret: 'keyboard cat', cookie: { maxAge: 60000 }}));
+
+app.use('/graphql', graphqlHTTP({
+ schema: MySessionAwareGraphQLSchema,
+ graphiql: true
+}));
+```
+
+Then in your type definitions, you can access the request via the third "context" argument in your `resolve` function:
+
+```js
+new GraphQLObjectType({
+ name: 'MyType',
+ fields: {
+ myField: {
+ type: GraphQLString,
+ resolve(parentValue, args, request) {
+ // use `request.session` here
+ }
+ }
+ }
+});
+```
+
+
+## Providing Extensions
+
+The GraphQL response allows for adding additional information in a response to
+a GraphQL query via a field in the response called `"extensions"`. This is added
+by providing an `extensions` function when using `graphqlHTTP`. The function
+must return a JSON-serializable Object.
+
+When called, this is provided an argument which you can use to get information
+about the GraphQL request:
+
+`{ document, variables, operationName, result }`
+
+This example illustrates adding the amount of time consumed by running the
+provided query, which could perhaps be used by your development tools.
+
+```js
+const graphqlHTTP = require('express-graphql');
+
+const app = express();
+
+app.use(session({ secret: 'keyboard cat', cookie: { maxAge: 60000 }}));
+
+app.use('/graphql', graphqlHTTP(request => {
+ const startTime = Date.now();
+ return {
+ schema: MyGraphQLSchema,
+ graphiql: true,
+ extensions({ document, variables, operationName, result }) {
+ return { runTime: Date.now() - startTime };
+ }
+ };
+}));
+```
+
+When querying this endpoint, it would include this information in the result,
+for example:
+
+```js
+{
+ "data": { ... }
+ "extensions": {
+ "runTime": 135
+ }
+}
+```
+
+
+## Additional Validation Rules
+
+GraphQL's [validation phase](https://facebook.github.io/graphql/#sec-Validation) checks the query to ensure that it can be successfully executed against the schema. The `validationRules` option allows for additional rules to be run during this phase. Rules are applied to each node in an AST representing the query using the Visitor pattern.
+
+A validation rule is a function which returns a visitor for one or more node Types. Below is an example of a validation preventing the specific fieldname `metadata` from being queried. For more examples see the [`specifiedRules`](https://github.com/graphql/graphql-js/tree/master/src/validation/rules) in the [graphql-js](https://github.com/graphql/graphql-js) package.
+
+```js
+import { GraphQLError } from 'graphql';
+
+export function DisallowMetadataQueries(context) {
+ return {
+ Field(node) {
+ const fieldName = node.name.value;
+
+ if (fieldName === "metadata") {
+ context.reportError(
+ new GraphQLError(
+ `Validation: Requesting the field ${fieldName} is not allowed`,
+ ),
+ );
+ }
+ }
+ };
+}
+```
+
+## Other Exports
+
+**`getGraphQLParams(request: Request): Promise`**
+
+Given an HTTP Request, this returns a Promise for the parameters relevant to
+running a GraphQL request. This function is used internally to handle the
+incoming request, you may use it directly for building other similar services.
+
+```js
+const graphqlHTTP = require('express-graphql');
+
+graphqlHTTP.getGraphQLParams(request).then(params => {
+ // do something...
+})
+```
+
+
+## Debugging Tips
+
+During development, it's useful to get more information from errors, such as
+stack traces. Providing a function to `formatError` enables this:
+
+```js
+formatError: error => ({
+ message: error.message,
+ locations: error.locations,
+ stack: error.stack ? error.stack.split('\n') : [],
+ path: error.path
+})
+```
